VOLTHAの環境構築と試し方
VOLTHAとは
VOLTHA (Virtual OLT Hardware Abstraction) とは、光アクセス装置の仮想化を実現するためのオープンソースソフトウェアで、ベンダー毎やPON標準毎に異なる装置の制御や管理情報を抽象化する機能を持ちます。VOLTHAは一つのソフトウェアではなく、VOLTHAコア、アダプタ、kafka、etcdなどの複数の構成要素が連携することで動作します。また、実際の光アクセス装置の実機がなくても、BBSimというOLT、ONUのシミュレータがあり、サーバ内だけで構築し、試してみることができます。これらのソフトウェア環境の構築方法は2つ用意されており、Docker構成もしくはkubernetes構成で動作させることができます。環境構築方法と簡単な動作確認の方法を説明します。
サーバの環境構築
VOLTHAの推奨されている動作環境の構築方法を下に示します。
Ubuntu 16.04 or 18.04においてディストリビューションとパッケージの更新を行います。
sudo apt update
sudo apt dist-upgrade
Dockerとビルドツールのインストール。
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install build-essential docker-ce git
docker-composeのインストール。
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod 755 /usr/local/bin/docker-compose
Go言語のインストール。
sudo add-apt-repository ppa:longsleep/golang-backports
sudo apt update
sudo apt install golang-1.13
環境設定。(exportの部分は~/.profileにも設定し、永続化する。)
mkdir $HOME/source
mkdir $HOME/go
export GO111MODULE=on
export GOPATH=$HOME/go
export DOCKER_TAG=latest
export PATH=$PATH:/usr/lib/go-1.13/bin:$GOPATH/bin
go version
Dockerをsudoなしで使うための設定。（一度ログアウトが必要）
sudo usermod -a -G docker $USER
kubernetes構成ではjqとyqを使用しますのでインストールします。 yqがsnapでしかインストール出来なかったので以下のようにしています。
sudo apt install jq
sudo apt install snap
sudo snap install yq
Docker構成の環境構築
VOLTHA core部分のソフトウェアのリポジトリ内にコンテナ一式を立ち上げるためのymlファイルがありますので、それを編集します。 https://github.com/opencord/voltha-go/blob/master/compose/system-test-bbsim.yml 以下のように書き換えます。
${DOCKER_REGISTRY}${DOCKER_REPOSITORY}→voltha/${DOCKER_TAG}→VOLTHAのバージョン毎に各構成要素のバージョンの組み合わせが異なるので、VOLTHA docsで試したいVOLTHA Componentのバージョンを確認し、一つ一つ記載する。- BBSimのオプション指定方法が変更されており、
-auth→-authRetry,-dhcp→-dhcpRetryと変更する。
VOLTHA2.5を動作させたい時のymlファイルを示します。
